STOVE.

SPECIFICATION forming part of Letters Patent No, 311,653, dated February 3, 1885.

Application tiled February 2, 1894. (No mr del.)

fo all whom t may concern.-

Beit known that I, MILES W. Gnnnnnmof Detroit, in the county of Vayne and State of Michigan, have invented new and useful Improvenients in Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part vof this speciiication.

This invention relates to certain new and useful improvements in that class of stoves in which combustion takes place at the base of a column of fuel sustained and delivered by and from a magazine, and commonly called basei5 burning stoves.

The objects of the invention are, first, to provide an effectual cut-off in the magazine that will shut off the supply of fuel in the magazine and prevent its discharge upon thel 2o incandescent fuel in the lire-pot, and, second, in so constructing the magazine in sections, one sliding upon the other, that the lower end section may be raised clear' from the tire below, thereby preventing` any danger of burning olf at the lower end, and converting` a base-burner into a surface-burner.

To this end the invention consists in the peculiar construction and arrangement of the parts forming the cutoff, and in the construction and arrangement of the magazine-sections, all as more fully hereinafter described.

Figure lis a vertical central section with cutoff open and mouth section or sleeve ofthe magazine lowered. Fig. 2 is a similar view with cut-off closed and mouthsection of the magazine raised. Fig. 3 is a vertical section on 'the line X X in Fig. 2. Fig. 4 is a side eleration of Fig. 2, showing the position of the toggle-levers when the mouth-section ofthe magazine is raised. Fig. 5 is a perspective view of the segmental plates detached. Figs. 6 and 7 are details.

In the accompanying drawings, which form a part of this specification, A represents the magazine proper, and is designed to be hung from the so-called middle ring of the stove or from the top, such position being determined by the style of the stove in which such magazine is to be placed.

B C represent two segmental plates, the 5o former of which is provided with the trunnions b b', which pass through proper openings in the wall of the magazine A, near the lower end, the end ofthe trunnion b being squared to receive a wrench. The arms or wings o of the plate C have formed in them the U -shaped openings d, which, when in place, slip over the trunnions of the plate B.

A stop, e, upon the outer face of the plate C, impinging against theinner wall of the maga- 6o zine, prevents such plate falling loelow a given point. We will now suppose that the maga zine is filled with coal and the parts are in the position shown in Fig. l. If it is desired now to cut off the supply ot' coal from the 65 combustion-chamber, the wrench is applied to the trunnion b. The latter is partially rotated until the plate B is in the position shown in dotted lines in Fig. l. At this pointalug, h, upon the trunnion comes in contact with 7o the lower side ofthe U -shaped arm of the plate C, when, upon giving a further turn with the wrench,the parts are compelled to assume the positions shown in Fig. 2, the outer edge ofthe plate B resting upon a stop, fi, projecting from 7 the inner wall of the magazine proper,A. By leveling off the surface of the coal now in the fire-pot we have by the means described converted our base-burning self-feed magazinestove into a surface-burner. demonstrated that a stove provided with a cut-off' oi' this character can be run more economically in point of fuel, a greater .radiation oflight and heat being had in the surface burning. It has also been demonstrated that the lower end of the `magazine below the Vcutbii" from its close proximity to the incan- Practice has So trunnions b b of the cut-off plate B project. as shown. Upon each of these trunnions I secure'oneend ofthe lever E in any convenient manner, so that it has a positive movement with the trunnions. In the oppposite end ofthis lever I pivotally secure a lever, F, which in turn is pivoted to the sleeve D near its upper edge. It will be observed that when the sleeve is in its lowest position the levers stand relativelyin theposition shown in dotted lilies in Fig. 1. By partially rotating the trunnions by means ofa suitable wrench, as herein described, for closing the cuto'f,the sleeve D is caused through the action of the levers to slide up on the magazine proper, thereby withdrawing this portion thereof from a close proximity to the tire and preventing its being burned off'. l

While I have described and illustrated my l invention as connected to acylindrical magazine, it is evident that it can readily be adapted to any style or shape ot' magazine, or that the cut-off and sleeve may be arranged to opcrate separately without departing from the spirit of my invention. l What I claim as my invention isl. The combination, with a magazine of a I stove, of' two segmental cut-off plates and means for partially rotating such plates in the same direction, substantially as and for the 3o purposes described.

2. The combination, with a magazine of a stove, of a slotted sleeve at the discharge end of such magazine, and the levers E, secured to the trunnions b b. passing through the slots in said sleeve, and the levers F connectingV said levers E with said sleeve, for vertically raising or lowering such sleeve upon the magazine, substantially as described.

3. The combination, in a magazinestove,of an extensible magazine in two or more sections, the lower one of which can be projectedor retracted, and a cut-offin the upper section ofsuch extensible magazine, said eXtension and cut-ott' being connected to operate together, substantially as and for the purposes specilied.

4. The combination, in a magazinestove. of the magazine A and two segmental cutoff plates, B C, arranged to be partially rotated in the same direction by the opera-tion ofthe trunnions common to both, substantially as Sct forth.
